RESUMEN
BACKGROUND: No evidence-based therapy has yet been established for Takotsubo syndrome (TTS). Given the putative harmful effects of catecholamines in patients with TTS, beta-blockers may potentially decrease the intensity of the detrimental cardiac effects in those patients. OBJECTIVE: The purpose of this study was to assess the impact of beta-blocker therapy on long-term mortality and TTS recurrence. METHODS: The cohort study used the national Spanish Registry on TakoTsubo Syndrome (RETAKO). A total of 970 TTS post-discharge survivors, without pheochromocytoma, left ventricular outflow tract obstruction, sustained ventricular arrhythmias, and significant bradyarrhythmias, between January 1, 2003, and July 31, 2018, were assessed. Cox regression analysis and inverse probability weighting (IPW) propensity score analysis were used to evaluate the association between beta-blocker therapy and survival free of TTS recurrence. RESULTS: From 970 TTS patients, 582 (60.0%) received beta-blockers. During a mean follow-up of 2.5±3.3 years, there were 87 deaths (3.6 per 100 patients/year) and 29 TTS recurrences (1.2 per 100 patient/year). There was no significant difference in follow-up mortality or TTS recurrence in unadjusted and adjusted Cox analysis (hazard ratio [HR] 0.86, 95% confidence interval [CI] 0.59-1.27, and 0.95, 95% CI 0.57-1.13, respectively). After weighting and adjusting by IPW, differences in one-year survival free of TTS recurrence between patients treated and untreated with beta-blockers were not found (average treatment effect -0.01, 95% CI -0.07 to 0.04; p=0.621). CONCLUSIONS: In this observational nationwide study from Spain, there was no significant association between beta-blocker therapy and follow-up survival free of TTS recurrence.

Background: Severe residual shunts after percutaneous closure of atrial septal defects are unusual. These patients are usually considered candidates for surgery. Case summary: We describe the transjugular closure of a residual atrial septal defect with significant left-to-right shunt due to a malpositioned large atrial septal device in a symptomatic 74-year-old female. Transjugular access was chosen first due to the unfavourable position of the device for delivery of a new one from the femoral approach. An overlapping Figulla® Flex II 27/30â mm PFO device was successfully implanted with the guidance of 3D-transoesophageal echocardiography. Discussion: This case demonstrates the safety and feasibility of transjugular access as an alternative to femoral or transhepatic approaches in patients with difficult atrial septal anatomies, who are usually referred for surgery.
RESUMEN
OBJECTIVES: Elderly patients show a higher incidence of ischemic and bleeding events after percutaneous transluminal coronary intervention (PCI). We sought to investigate outcomes in elderly patients treated with antithrombotic strategy guided by bleeding and ischemic risks after revascularization with last generation everolimus-eluting stent (EES). METHODS: Prospective multicenter registry including patients over 75 years revascularized with EES and antithrombotic therapy guided by clinical presentation, PCI complexity and PRECISE DAPT score. Co-primary safety endpoints were: (1) composite of cardiac death, myocardial infarction and stent thrombosis and; (2) bleeding (BARC 2-5). Primary efficacy endpoint was target lesion revascularization. A matched group of patients revascularized with current drug-eluting stents and no such tailored antithrombotic therapy was used as control. RESULTS: Finally, 1064 patients were included in SIERRA-75 cohort, 80.8 ± 4.2 years, 36.6% women, 71% acute coronary syndromes (ACS) and 53.6% complex PCI. Co-primary safety endpoint of major adverse cardiovascular events was met in 6.2%, co-primary safety endpoint of bleeding in 7.8% and primary efficacy endpoint of TKLR in 1.5%. The multivariable adjusted model showed no significant association of the prescribed short/long dual antiplatelet therapy (DAPT) durations with any endpoint suggesting a well tailored therapy. No stent thrombosis reported in the subgroup with 1-3 months DAPT duration. As compared to control group, bleeding BARC 2-5 was significantly lower in SIERRA-75 group (7.4% vs. 10.2%, P = 0.04) as well as the net safety-efficacy endpoint (14.3% vs. 18.5%, P = 0.02). CONCLUSIONS: In elderly population, the application of this risks-adjusted antithrombotic protocol after revascularization with last generation EES seems to be associated with an improved prognosis in terms of ischemic and bleeding outcomes.
RESUMEN
Platelet glycoprotein IIb/IIIa inhibitors (GPIs) have been part of the adjuvant treatment of acute coronary syndrome for years. However, real-life data regarding the efficacy and safety of GPIs under the current indications are lacking in the setting of potent platelet inhibition. The objectives were to assess the efficacy and safety of abciximab versus tirofiban in patients with ST-elevation acute myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) and pretreated with ticagrelor, and to identify independent predictor factors of efficacy, bleeding and platelet drop. Three hundred sixty-two patients were divided by GPI administered. Clinical, laboratory, angiographic and outcome characteristics were compared. The primary objective was a composite efficacy endpoint (death from any cause, nonfatal myocardial infarction and nonfatal stroke) at 30 days. The secondary objectives were its individual components, safety (bleeding) and the impact on platelet count during hospital stay. The composite efficacy endpoint was similar in the abciximab and tirofiban groups (6.1% vs 7.3%; p = .632). There were also no differences in cardiovascular death (2.5% vs 2.4%; p = .958), nonfatal myocardial infarction (3% vs 4.3%; p = .521) and nonfatal stroke (0.5% vs 1.8%; p = .332). Tirofiban administration was associated with a higher incidence of bleeding (11.6% vs 22%; p = .008) with no differences in BARC ≥ 3b bleeding (3.6 vs 2.5%; p = .760). In STEMI patients undergoing PPCI with ticagrelor, abciximab and tirofiban had similar rates in the composite efficacy endpoint at 30 days. The 30-day bleeding rate was significantly higher in the tirofiban group. Tirofiban administration was an independent predictor of both bleeding and platelet count drop.

BACKGROUND: Takotsubo cardiomyopathy is a non-ischemic cardiomyopathy characterized by acute left ventricular systolic dysfunction with transient wall motion abnormalities without a culprit coronary stenosis or other concurrent diagnoses. Its coexistence with transient high-degree AV block is very infrequent. CASE PRESENTATION: A 61-year-old man presented with a new onset of high degree AV block without ST segment deviations developing an anterior and apical dyskinesia with a low left ventricular ejection fraction in the absence of coronary artery disease. CONCLUSION: Atrioventricular block is an uncommon presentation of Takotsubo syndrome. The management of patients with relevant conduction disorders in this scenario is a challenge for the clinician. In case of persistence of advanced conduction disorders, it seems appropriate to implant a pacemaker.
RESUMEN
Background Takotsubo syndrome (TTS) is an acute reversible heart condition initially believed to represent a benign pathology attributable to its self-limiting clinical course; however, little is known about its prognosis based on different triggers. This study compared short- and long-term outcomes between TTS based on different triggers, focusing on various physical triggering events. Methods and Results We analyzed patients with a definitive TTS diagnosis recruited for the Spanish National Registry on TTS (RETAKO [Registry on Takotsubo Syndrome]). Short- and long-term outcomes were compared between different groups according to triggering factors. A total of 939 patients were included. An emotional trigger was detected in 340 patients (36.2%), a physical trigger in 293 patients (31.2%), and none could be identified in 306 patients (32.6%). The main physical triggers observed were infections (30.7%), followed by surgical procedures (22.5%), physical activities (18.4%), episodes of severe hypoxia (18.4%), and neurological events (9.9%). TTS triggered by physical factors showed higher mortality in the short and long term, and within this group, patients whose physical trigger was hypoxia were those who had a worse prognosis, in addition to being triggered by physical factors, including age >70 years, diabetes mellitus, left ventricular eyection fraction <30% and shock on admission, and increased long-term mortality risk. Conclusions TTS triggered by physical factors could present a worse prognosis in terms of mortality. Under the TTS label, there could be as yet undiscovered very different clinical profiles, whose differentiation could lead to individual better management, and therefore the perception of TTS as having a benign prognosis should be generally ruled out.

OBJECTIVES: This study sought to describe the incidence, determinants, and prognostic impact of cardiogenic shock (CS) in takotsubo syndrome (TTS). BACKGROUND: TTS can be associated with severe hemodynamic instability. The prognostic implication of CS has not been well characterized in large studies of TTS. METHODS: We analyzed patients with a definitive TTS diagnosis (modified Mayo criteria) who were recruited for the National RETAKO (Registry on Takotsubo Syndrome) trial from 2003 to 2016. Cox and competing risk regression models were used to identify factors associated with mortality and recurrences. RESULTS: A total of 711 patients were included, 81 (11.4%) of whom developed CS. Male sex, QTc interval prolongation, lower left ventricular ejection fraction at admission, physical triggers, and presence of "a significant" left intraventricular pressure gradient, were associated with CS (C index = 0.85). In-hospital complication rates, including mortality, were significantly higher in patients with CS. Over a median follow-up of 284 days (interquartile range: 94 to 929 days), CS was the strongest independent predictor of long-term, all-cause mortality (hazard ratio [HR]: 5.38; 95% confidence interval [CI]: 2.60 to 8.38); cardiovascular (CV) death (sub-HR: 4.29; 95% CI: 2.40 to 21.2), and non-CV death (sub-HR: 3.34; 95% CI: 1.70 to 6.53), whereas no significant difference in the recurrence rate was observed between groups (sub-HR: 0.76; 95% CI: 0.10 to 5.95). Among patients with CS, those who received beta-blockers at hospital discharge experienced lower 1-year mortality compared with those who did not receive a beta-blocker (HR: 0.52; 95% CI: 0.44 to 0.79; pinteraction = 0.043). CONCLUSIONS: CS is not uncommon and is associated with worse short- and long-term prognosis in TTS. CS complicating TTS may constitute a marker of underlying disease severity and could identify a masked heart failure phenotype with increased vulnerability to catecholamine-mediated myocardial stunning.

Introducción y objetivos: El síndrome de tako-tsubo es un proceso patológico potencialmente grave durante la fase aguda. Simula un infarto de miocardio, sin que haya lesiones coronarias potencialmente responsables. El objetivo de este trabajo es analizar la evolución y el pronóstico de los pacientes con síndrome de tako-tsubo en función del sexo. Métodos: Se analizaron las características de los pacientes incluidos en el registro RETAKO durante los años 2003 a 2015, un registro multicéntrico en el que participaron 32 hospitales españoles. Resultados: De los 562 pacientes incluidos, 493 (87,7%) eran mujeres. El dolor torácico fue menos frecuente como síntoma inicial en los varones que en las mujeres (43 [66,2%] frente a 390 [82,8%]; p < 0,01). El pronóstico fue peor en los varones, con mayor mortalidad intrahospitalaria (3 [4,4%] frente a 1 [0,2%]; p < 0,01), duración más prolongada de ingreso en cuidados intensivos (4,2 ± 3,7 frente a 3,2 ± 3,2 días; p = 0,03) y mayor frecuencia de insuficiencia cardiaca grave (22 [33,3%] frente a 95 [20,3%]; p = 0,02). Sin embargo la aparición de obstrucción dinámica a nivel del tracto de salida del ventrículo izquierdo se observó exclusivamente en mujeres (39 [7,9%] frente a 0 [0,0%]; p = 0,02) y la incidencia de insuficiencia mitral funcional también fue mayor en ellas (52 [10,6%] frente a 2 [2,9%]; p = 0,04). Conclusiones: El síndrome de tako-tsubo es una enfermedad que muestra grandes diferencias en función del sexo en cuanto a su incidencia, presentación y evolución, con un peor pronóstico en los varones
Introduction and objectives: Tako-tsubo syndrome is a potentially serious disease during the acute phase. It mimics myocardial infarction, but with no potentially causative coronary lesions. The aim of this study was to analyze the clinical course and outcome of patients with tako-tsubo syndrome by sex. Methods: We analyzed the characteristics of patients included in the RETAKO registry from 2003 to 2015, a multicenter registry with participation of 32 Spanish hospitals. Results: Of 562 patients included, 493 (87.7%) were women. Chest pain was less frequent as an initial symptom in men than in women (43 [66.2%] vs 390 [82.8%]; P < .01). The prognosis was worse in men, with higher in-hospital mortality (3 [4.4%] vs 1 [0.2%]; P < .01), longer intensive care stay (4.2 ± 3.7 vs 3.2 ± 3.2 days; P = .03) and a higher frequency of severe heart failure (22 [33.3%] vs 95 [20.3%]; P = .02). However, dynamic obstruction at the left-ventricular outflow tract occurred exclusively in women (39 [7.9%] vs 0 [0.0%]; P = .02). The incidence of functional mitral regurgitation was also higher in women (52 [10.6%] vs 2 [2.9%]; P = .04). Conclusions: Tako-tsubo syndrome shows wide differences by sex in terms of its incidence, presentation, and outcomes. Prognosis is worse in men

Introducción y objetivos: El síndrome de tako-tsubo es una entidad de etiología y epidemiología inciertas, capaz de semejarse a un infarto y que, aunque suele tener buen pronóstico, no está exenta de complicaciones. El objetivo del presente trabajo es caracterizar esta enfermedad en nuestro medio a través de un registro (REgistro nacional multicéntrico sobre síndome de TAKOtsubo). Métodos: El registro prospectivo incluyó a 202 pacientes incidentes en 23 hospitales entre 2012-2013. Se recogieron las características clínicas, analíticas, electrocardiográficas y de imagen, así como los eventos durante el seguimiento. Se incluyó a los pacientes cuando sus médicos consideraron probado el caso, y la incidencia de la enfermedad se calculó en función de los cateterismos solicitados con el diagnóstico presunto de síndrome coronario agudo. Resultados: Los casos fueron predominantemente mujeres (90%), con una media de edad de 70 años y frecuentes factores de riesgo cardiovascular, hipertensión arterial (67%), dislipemia (41%), diabetes mellitus (15%) y tabaquismo (15%). Sin clara distribución semanal o estacional, se calculó una incidencia del 1,2%. El dolor torácico fue el síntoma predominante, con algún desencadenante (psíquico, físico o ambos) en el 72%, y la mayoría consultó en las primeras 6 h. La estancia mediana fue de 7 días; apareció algún síntoma de insuficiencia cardiaca en el 34,0% y arritmias en el 26,7% y murió el 2,4%.ConclusionesEl síndrome de tako-tsubo es una enfermedad poco incidente, que afecta predominantemente a mujeres posmenopáusicas, en más de la mitad de los casos tras una situación psicológicamente estresante. Se caracteriza por dolor anginoso, sin distribución estacional; aunque no está exenta de morbimortalidad, conlleva buen pronóstico (AU)
Introduction and aims: The etiology and epidemiology of tako-tsubo cardiomyopathy remain uncertain. The symptoms of this condition are often similar to those of myocardial infarction and, although it usually has a good prognosis, it is not without complications. Our aim was to characterize this disease in our setting using a dedicated registry (Spanish REgistry for TAKOtsubo cardiomyopathy). Results: The patients were predominantly women (90%), with a mean age of 70 years, and many had cardiovascular risk factors, such as hypertension (67%), dyslipidemia (41%), diabetes mellitus (15%), and smoking (15%). The incidence of tako-tsubo cardiomyopathy was 1.2%, and there was no clear weekly or seasonal distribution pattern. Chest pain was the predominant symptom, a triggering factor (emotional, physical, or both) was present in 72%, and most patients consulted within the first 6 h after symptom onset. The median duration of hospitalization was 7 days. There were heart failure symptoms in 34.0%, arrhythmia in 26.7%, and 2.4% of patients died. Conclusions: The incidence of tako-tsubo cardiomyopathy is low. This disease primarily affects postmenopausal women, and occurs after a situation of emotional stress in more than half of affected individuals. It is characterized by anginal pain, shows no seasonal distribution, and has a good prognosis, although it is not without morbidity and mortality (AU)

La fibrilación auricular es la arritmia más frecuente en el período peri-infarto agudo de miocardio, aunque su presencia asociada tan solo a la fase de isquemia aguda y su inmediato cese tras una revascularización precoz y efectiva es testimonial en la literatura, con la consiguiente falta de evidencia para su posterior tratamiento. Se presenta un caso clínico en el que el intervencionismo coronario precoz consiguió la cardioversión a ritmo sinusal de una fibrilación auricular en el curso de un infarto agudo de miocardio, posteriormente se discute la estrategia a seguir en torno a la arritmia en un paciente con buena evolución clínica tras el suceso(AU)

Introducción y objetivos: La eficacia de la administración conjunta de suero salino isotónico y N-acetilcisteína presenta resultados dispares en la prevención de la nefropatía por contraste yodado. Nuestro objetivo fue valorar la posible eficacia de esta estrategia combinada en pacientes con alto riesgo de desarrollar nefropatía inducida por contraste, ingresados y sometidos a intervencionismo coronario percutáneo por síndrome coronario agudo sin elevación del segmento ST en nuestro centro. Método: Se aplicó esta estrategia en los pacientes referidos, con al menos un factor de alto riesgo para desarrollar la nefropatía inducida por contraste: mayores de 80 años, diabetes mellitus, creatinina basal mayor de 1,5 mg/dl o alto volumen de contraste (mayor de 400 ml). El protocolo se aplicó durante 12 meses (pacientes que recibieron el protocolo de prevención) y se comparó con similares pacientes en los 12 meses previos que no recibieron profilaxis. Resultados: Un total de 30 pacientes (24 por ciento) desarrollaron nefropatía inducida por contraste. El porcentaje fue significativamente mayor en el grupo que no recibió profilaxis: 35,9 por ciento vs. 11,5 por ciento (p = 0.003). Conclusiones: La combinación de N-acetilcisteína por vía oral e hidratación parenteral en pacientes de alto riesgo, con síndrome coronario agudo sin elevación de ST, podría ser beneficiosa para evitar la aparición de la nefropatía inducida por contraste(AU)
